Abstract

Die Erfindung betrifft eine von der Umgebung abgedichtete Schaltkammer, in der elektrische Kontakte und wenigstens ein poröser Getter untergebracht sind, wobei als Getterstoff eine Substanz verwendet ist, die bezüglich auf den Kontakten fremdschichtbildender Stoffe Adsorptionskräfte besitzt. Die Verwendung von Gettern in dicht abgeschlossenen Kontaktkammern von Relais und Schaltern dient dem Zweck, fremdschichtbildende Moleküle wie z.B. organische Verbindungen von den Kontakten fernzuhalten und langzeitig und selektiv an sich zu binden. Dem trägt die Erfindung dadurch Rechnung, daß die Poren des in der Schaltkammer befindlichen Getterstoffes überwiegend größer als 3 nm und kleiner als 100 nm gewählt sind und daß der Mittelwert der Porendurchmesser im Bereich von etwa 7-20 nm liegt.The invention relates to a switching chamber which is sealed off from the environment and in which electrical contacts and at least one porous getter are accommodated, a substance being used as the getter substance which has adsorption forces with respect to substances forming foreign layers on the contacts. The use of getters in tightly sealed contact chambers of relays and switches is used to keep foreign layer-forming molecules such as organic compounds away from the contacts and to bind them selectively over the long term. The invention takes this into account in that the pores of the getter material located in the switching chamber are selected predominantly larger than 3 nm and smaller than 100 nm and that the mean value of the pore diameter is in the range of about 7-20 nm.
